Question

Fill in the blank with the most appropriate option:
How long have you been working ______ the hospital?

• A. this
• B. that
• C. at
• D. next door

Answer 1

The correct option is C at

A preposition is a word that connects another word (noun, pronoun, verb, etc.) to the rest of the sentence.

Option C: The preposition 'at' refers to place. The word applies to the given sentence, the place being the 'hospital'. Hence option C is correct.

Options A and B: 'This' and 'that' are pronouns that indicate places that are near and far, respectively. They aren't prepositions, hence A and B are incorrect.

Option D: 'Next door' is an adverb that indicates place. But for the given sentence, a preposition is required. Hence option D is incorrect.
